Vacuum tube solar collectors generally utilize the sun's energy efficiently, and the vacuum helps minimize heat loss to the environment. The copper insert on the inside of the vacuum tube helps the solar energy to be absorbed and transmitted faster in the system. Solar collectors of this type can be used to produce hot water and supplement heating systems.
This product - due to its fragility - can only be delivered in a unit package.
